Zionism is a political movement, a national ideology. Its history is one of national liberation but also of tragedy, a tragedy faced by two peoples with equally legitimate aspirations to the same piece of territory. In order to help understand that tragedy as well as, one day, how it may perhaps be overcome, a morphological analysis of Zionism is undertaken. The morphological approach to the study of ideologies was first developed by Michael Freeden. Applied to Zionism, it reveals four core concepts of the ideology - nation, antisemitism, galout and national renaissance. Their analysis aims to account for the conceptual evolution of Zionism both diachronically and as regards its numerous ideational variations, thus providing an account of how it evolved through a changing sociopolitical context.
